`'The invention relates to improvements in combination humidiliers anddecarbonizers and an obiect. of the invention is to provide a devicewhich can be readily attached to the customary radiator of an automobileand View. the invention consists essentially in the.

connected with the intake manifold thereof and which will supply hotvapor to mix with the firing mixture passing to the cylinder, therebyimproving the firing mixture and also preventing the accumulation ofcarbon within the cylinder. Y

A further object: of the invention is to embody t-he device as part ofthe radiator cap so that it can be readily removedl and such that it isat all times visible to the driver.

A further object is to construct the device in a simple, durable andinexpensive man-ner and such that it will not interfere in any way withthe present car construction.

.A further object is to construct the device so that there is nopossibility of water flooding into the manifold from the radiatorthrough the device and a further object is to provide a device with avalve controlling the vapor passing to the manifold and actuated.

from the dash. Y

Vith the above more important objects in arrangement and construction ofparts hereinafter more yparticularly described, reference being had tothe accompanying drawing iu which: l

Fig. 1 is a side view of the front part of an automobile equipped withmy invention, the hood being broken away and the dash and foot boardsbeing, shown in vertical section.

Fig. 2 is an enlarged detailed vertical sectional view centrally throughthe device.

Fig. 3 is an enlarged detailed sectional view centrally through t-hehose connecting the endsof the pipe. l v

Fig. 4 is a perspective view of certain parts showing the manner inwhich they are formed and how they are assembled. v

In the drawing like characters of reference indicate corresponding partsin the several figures.

The automobile presents the customary radiator 1, intake manifold 2,engine Vhood '3, dash l and foot boards 5, these being of ordinaryconstruction and on such account not further detailed.

The radiator presents the usual filling r opening 6 which is enclosed bythe customary exteriorly screw threaded upstanding annular flange 7. Theusual radiator cap threads onto thisange. my case, however, the cap isformed as part of my device.

The cap 8 which is in reality the base of my device is adapted to screwthread Lonto the flange and lit is vprovided with two outstandingdiametrically opposed hand grips 9 and 10 which facilitate in thescrewing up or unscrewing of the cap. The body of the.

cap is provided on the top side with an up- Y standing marginal flange11 within which I seat a cylinder 12. which 'is preferably transparent.have found a glass cylinder serves my purpose. vA gasket 13 is placedbeneath the cylinder. A flanged topor cover is placed overthe upper endyof the cylinder l v17 andaccordingly holds the coverand cylindertightly. in place.

The cap 18 is cylindrical `and it is provided with an extendinghexagonal head 19. On the cylindrical body of the cap 18, I mountslidably a disc20 having a slight boss 21; which prevents the tiltingofthe disc. :The disc under certain lconditions is adapted to moveV upand close the lower ends of holes or ducts 22 and 23 passingthrough thebody of the cap 8 and opening to the interior of the cylinderv 12. Thetube orpipe 16 is provided .within the cylinder 12 `and ladjacent thecover 14 with a vhole orduct 24e and the upper end of the tube isprovided with ak seat 25 adapted to receive a ball `valve 26. A shortsleeve 27 is screw threaded to the up? per 'end of the tube and forms a'valve casing. A pipe 28 whichis really an extension of the pipe 16beyond the valve is screw threaded to the sleeve andis connected by alength of hose`29 to a further pipe/30, the latter pipe opening to theinterior of the intake manifold 2. The pipe 30 passes through the hoodin a location adjacent the rear side of t-he radiator and preferably atthe customary I top hinge of the hood'as I find at this location thereis usually a place where one can pass a small pipe through withoutactually having to drill a hole and further by passing it through atthis point, the hinge is not interfered with. It will be observed thatthe length of hose V29 is above the hood. This arrangement permits me toreadily disconnect the pipes 29 and 30 by slipping the hose endwise onthe pipe 29 after which one can remove the device from the radiator byunscrewingthe cap 8; In order to prevent the ball valve from seatingagainst the lower end of the pipe 28, I have passed a pin 31 across thispipe. kA controlling valve 32 of any approved type is inserted in thepipe 30 and presents a lever 33 to which I attach a push rod 34 passingslidably through the dash and fitted with a finger grip 35. y

When the device is in Vuse and the engine is initially started,onefkeeps the `valve 32 closed' After the engine has'warmed up and thewater in the `radiator has become heated andris giving off water vaporor steam, the Valve 32 can be opened by manipulating the pushrod 34:from the dash. When'this occurs the suctionfrom the engine cylinderswill raise the valve 26 from its seat and will draw the hot vapor fromthe radiator through the. ports 22, 23 and 24 and pipes and discharge itinto the intake manifold where it mixes with the ingoing firing mixture.This hot vapor gives a much more eflicient tiring mixture and alsoprevents the formation of carbon within the cylinder and particularly onthev spark plugs.

f One can control the amount of vapor admitted to the intake manifold byopening the valve 32 a greaterl or less amount as conditions warrant. i

Under certain road and engine conditions, there is a possibility of thevwater in the radiator boiling and in order to pre-vent this entering theint-akemanifold, I have provided the disc 20 which is adapted'whenstruclby the' boiling water to fly up and seat against the under side ofthe body of the cap 8 and in so'doing close the openings 22 and 23. y l

Obviously the device can be readily re- Y moved'irom the radiator whenit is desired to place more water in the radiator and the driver is atall times able to see just how the device is functioning as he can seethe steam rising in the cylinder 12. e

Whilst I have described the cap 8 as interiorly screw threaded to fit anexterior screw threaded flange 7, it will be readily understood that thecap 8 could be modiied to fit the various existing types of flangespresented by the varying radiators.

VVh'at I claim as my invention is:
